One date drives everything
For a sale, it’s completion. For a tenancy, it’s the day the lease ends and the next person gets the keys. Work backwards from that date: the clearing, any repairs, and the final clean each need their own slot, and the clearing has to come first, because the other two can’t happen around furniture.
Leave slack in the last week. The final tenth of a home, the storeroom, the tops of the wardrobes, the household shelter, is where clearing always slows down, and it’s better to find that out with days to spare than on the morning of the handover.
Put what stays in writing
Most handover disputes aren’t about what was left behind but about whether it was supposed to be. A buyer may have agreed to take the wardrobes; a tenant may have been told the fridge could stay. If the sale documents or the tenancy agreement list what stays, that list settles it. If they don’t, agree it in writing before the handover date, not at the inspection.
